Did my grandma have dark spirits in her house ?

my auntie & my grandma used to see shadows & see them run around, tey would also throw things off of tables but very rarely. then awhile later my uncle stayed with them for awhile & it seemed the spirit got angry, such as bushing a stereo off of the table & throwing other stuff off more often. & just after awhile nothing happened again. they think he scared it off ? which doesnt surprise me cause my uncle is hell feral & selfish. maybe because he was taking control of my grandma (my grandma does everything for him & her excuse is that she gets carers payment for it, even though shes been doing it for way before she started getting paid) that made it angry (& maybe his smelly too)
